CENTRIFUGAL MACHINE.

Speccaton of Letters Patent.

Patented Feb. 11, 1908.

Application filed March u126,1906. Serial No. 308.973.

4To all whom it may concern:

Be it known that I, WILLIAM L. DOLIER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State 'ofPennsylvania, have invented certain new and useful Improvements inCentrifugal Machines, of which the following is a specification.

My invention relates to centrifugal separating or drying apparatus,involving the principle, well understood in the art, of separatingliquids from solids, liquids from liquids, etc., by rapidly rotating thematerials to be dried or separated.

It is the object of my invention to provide an efficient and compactarrangement of centrifugal machine which may be conveniently driven bysteam, or any suitable motor, there being provided for use when desireda heating chamber surrounding the usual curb, such heating chamberhaving steam circulating therethrough or containing an electrical heateror provided with any other heating agency.

It is the object of my invention to provide in a steam driven machine,means for heating the contents of the centrifugal basket and allowingthe steam, either live or exhaust, to pass out through a hollow shaftupon which the centrifugal basket is mounted.

My invention residesv also in other features hereinafter described andpointed out in the claims.

For an illustration of one form my invention may take, reference is tobe had to the accompanying drawing.

A pedestal 1, preferably of cast iron, has secured to its top, by bolts3, 3, a casting of sheet metal curb member 4 provided with an inner wallplate 5 forming the curb proper surrounding the centrifugal basket 6.basket is secured by a taper ft upon the upper end of the hollow shaft 7by means of the perforated cap 8 which is screw threaded and engages thescrew threads at the upper end of the shaft 7. The shaft 7 has upon itat its lower end, the collar or shoulder 9 resting upon the superposedwashers 10, 11 and 12 resting upon the casting or plate 13 secured bybolts 14, 14 to the lower end of the hanger 15 secured by bolts 16,16'to the underside of the top plate 2 of pedestal 1. The hanger 15 isbored out and babbitted as shown at 17 to form a bearing for the outsideof the hollow shaft 7. In the compartment 1S between the casting 4 andplate 2 and This l mounted upon the hollow shaft 7 is the steam turbinewheel 19 the steam for which is supplied by a nozzle 20 forming acontinuance of the steam pipe joint 21. A -stufling box or gland 22 isprovided in the bottom of the curb chamber to accommodate the passagetherethrough of the hollow shaft 7.

Extending well up into the inside of the hollow shaft 7 is the pipe 23which is screw threaded into the member 13 and has an elbow or otherconvenient joint 24 for attachment of a. suitable pipe leading away fromthe machine.

Small lengths of exteriorly screw threaded .pipes 25 and 26 communicatebetween the turbine wheel and compartment and the curb chamber andheating chamber respectively. These short lengths are accessible by handholes having suitable covers 27, and are provided with caps 28 which maybe interchanged in any suitable combination as hereinafter described.

The casting 13 has an oil tight joint with the member 15 so that thewasher bearing of the hollow shaft is maintained flooded with oilwhichstands in the bearing 17 and fills more or less of the depression orreservoir 15 in the top of the member 15.

The operation is as follows: The steam issuing from the nozzle 20strikes the blades of the turbine wheel 19 and thereby rotates thebasket 6 and its contents at a high rate of speed. The exhaust steamfrom the turbine may, when the caps 28 are on the short pipes 26, (thuscutting off communication with the heating chamber 4 pass through theshort pipes 25 into the curb chamber, which is closed by the cover 29,thus heating the perforated basket wall 6 and thence passing through thetop of the basket into the interior thereof to further heating thecontents and thence passing through theperforated cap 8 through theVhollow shaft 7 and thence through the exhaust pipe 23 to some externalpoint. The pipes 25 and 26 may be open at the same the steam to pass asjust described, while a portion will pass into the heating chamber 4 andout through exhaust port 30. Or the short pipes 25 may be closed by caps2S, and all of the exhaust steam may pass into the heating chamber 4 andthence through the exhaust opening 30. When the heating agent is passingthrough or inclosed in the heating chamber 4, heat is communicatedthrough the curb wall 5 tothe interior of the time thus allowing aportion of means permitting the exit curb and through the perforatedwall 6 of the basket and its contents. Or the turbine may exhaustdirectly to the outer air and live steam may be employed in either orboth the curb chamber or the heating chamber 4. If desired the heatingchamber 4 may be omitted., and the compartment 18 also.

In place of using steam as the heating agent in the chamber 4', anelectric heater may be inclosed therein if desired, or any other sourceof heat may be employed. The liquid thrown through the perforations ofthe wall 6 of the basket is collected on the bottom of the curb andcarried away by the pipe 31. yThe level of the outlet pipe 31 in thecurb 5 should be lower than the' top of the short pipes 25, to insurethat none of the separated liquid will pass into the turbine chamber 18.

What I claim is 1. In combination, a rotatable hollow shaft, acentrifugal basket secured thereto, a perforated cap within the basketand secured upon sald shaft, means for admitting a heating agent to saidbasket, and a pipe extending into said hollow shaft, whereby saidheating agent may pass out through said cap,

hollow shaft and pipe.

2. In combination, a rotatable hollow shaft, a centrifugal basketsecured thereto, a perforated cap secured upon said shaft within saidbasket, an exhaust pipe communieating with said hollow shaft, a steammotor driving said hollow shaft, and means for admitting exhaust steamfrom said motor to said basket, said steam adapted to 'heat the contentsof the basket and to ass out through said cap, hollow shaft an exhaustpg. In combination, a rotatable shaft, a centrifugal basket securedthereto within a curb chamber, the rotatable element of a fluid motorsecured upon said shaft in a chamber independent of said curb chamber,and means for permitting escape of exhaust fluid from said motor afterpassing through said basket.
